Naphthalene Sulfonate Formaldehyde (PNS)
(Na2SO4 ≤18%)
Description
PNS, a high range water reducer with no air entraining component, is also named as Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. It complies with chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.
Application
1. PNS is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement.
2. PNS is applicable in areas with the daily lowest temperature of 0℃ and for making concrete which requires high fluidity, high strength or steam curing.
3. PNS can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. PNS can be used as a raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.
5. PNS is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.

- Q: Who knows the inorganic insulation mortar and the previous material What is the difference?
- Good durability, good weatherability good hydrophobicity, strong vapor permeability high refractory grade, non-combustible good adaptability, easy construction, Speed, a comprehensive technology, practice diversity green, non-polluting, non-radiation ecological building materials Disadvantages: the current implementation of the standard is GB-2006 "building insulation mortar", this standard is the material standard, there is no specific system standards.
- Q: The use of cinder and other waste slag production of brick materials to enjoy what preferential policies
- Construction materials, refers to the brick (excluding sintered ordinary brick), blocks, ceramic, wall, pipe, concrete, mortar, road covers, road fence, fireproof materials, refractory materials, insulation materials , Waste residue refers to mineral processing waste residue, smelting waste residue, chemical waste residue and other waste residue The proportion of slag and the proportion of raw materials used in the production of raw materials, shall be calculated in terms of weight, shall not be calculated in terms of volume
- Q: Do the wall waterproofing can be directly on the brick brush on a layer of waterproof material on it
- Do the wall waterproofing can be directly on the brick brush on a layer of waterproof material on it
- Q: What is the difference between the insulation mortar and the ordinary mortar per square meter?
- Insulation mortar is used to enhance the insulation effect of a special mortar, in different construction projects, there are different design thickness, thickness of different prices per square meter is different
- Q: Construction site masonry mortar requirements M5 should be how to configure how the calculation is very urgent Thank you, ah
- Cement 32.5 (general) M5 mix ratio (weight ratio): cement: sand = 1: 5.23. Each cubic meter of brick masonry, the need for M5 cement mortar is 0.238m. of which 67.59Kg cement; sand 354Kg (0.26m3).
- Q: Cement mortar ground lining non-metallic wear-resistant material is what it means
- Used to repair often in the susceptible to wear, erosion, cavitation damage or chemical corrosion environment, equipment parts, metal surface repair, can also produce a variety of pre-wear anti-corrosion coating The use of temperature -50-150 ℃ 【wear-resistant metal repair agent performance characteristics】 ★ construction convenience, reduce downtime; ★ high strength with the metal substrate; ★ excellent single powder pole put mad borer Frost wear and And chemical resistance is more than 2 times the general metal; ★ fully cured after a variety of precision machining; ★ products to solve the emergency maintenance and a large number of equipment wear and corrosion problems, you can root run, run, drip, drain problems The The problem with the plastic just a little easier to worry-free, suitable for emergency repair purposes
- Q: What is the difference between a waterproofing agent and a waterproof coating?
- Waterproof coating contains waterproofing agent, waterproof mortar, waterproof emulsion. Waterproofing agent is just one type of waterproof coating!
- Q: Because before the paste with cement mortar, easy to fall, would like to ask if there is no other way to add the problem: it is better to say that the more detailed point
- Because before the paste with cement mortar, easy to fall, would like to ask if there is no other way to add the problem: it is better to say that the more detailed point
- Q: Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
- First of all, you can not replace the insulation material insulation, and many products in the development process slowly with the time will reflect their own shortcomings, insulation board has now been recognized by the state, and Insulation putty is not able to achieve the quality of the real ability to quantify. Insulation board normal life can reach 20 years, up to 30 years, the life of insulation putty is also 20 years, high water resistance can reach 30 years. Insulation putty can not be too thick construction, too thick easy to crack off, large area with the visual plane effect is poor. And the insulation board in the thickness of the greater arbitrariness, the insulation board in the construction of Ji Ji reclamation killing the old ghost tame handmade foam can make a large area of ??the wall is more smooth, of course, relatively heat putty, the construction cost is higher. But the two are complementary in the building, a small area more difficult to build the edge of the construction site, available insulation putty, large selection of insulation board, of course, for some of the insulation requirements are not high can also use insulation putty. The insulation requirements of a little more choice of insulation board. Insulation putty can replace the mortar, the premise is not to do other work above the putty. I hope my answer will help you!
- Q: Bags of dry powder polymer cracking mortar a cubic of the number of kilograms
- EVB insulation particles is an inorganic vitreous mineral material, is the highest quality volcanic rocks (pine rock ore) after multi-stage silicon carbide heating tube expansion of the production of glass furnace technology from processing, was irregular spherical particles , The internal porous cavity structure, the surface of the glass closed, shiny smooth, physical and chemical properties and stability, with light, adiabatic, fire, high and low temperature resistance, anti-aging, water absorption and other excellent features, is a high-performance environmentally friendly new inorganic Light insulation material
